The relay output contacts must not be connected to any utility connected circuits. Reinforced
insulation to the utility is required. The relay output contacts must have a maximum rating of
30 Vac/1A and 60 Vdc/2A nominal values.
Programmable Signal Inputs
The UPS incorporates two programmable signal inputs (see Figure 28 on
page 55). Use of non-polar (relay) control input is recommended. The
pins must be shorted with maximum resistance of 10 ohm in order to
activate the specific input.
NOTE
See Figure 39 on page 68 for the polarity and verify these connections if polarity
control is required.
The default and programmable settings for the signal inputs are shown
in Table 8.
